ALFRED KRAFFT AND EDw IiRn soo'r'T, or BROOKLYN, NEW YoRKZ' dteiameaabtaas Breasts aimless.

To (ZZZ whom cantata) Be it known that" we, ALFRED Katr na and EDwAIiD 'So o'r'r, citizens of and the United States, respectively, residing at Brooklyn, inithe' county of Kings, St-ateof New Yorlghave invent'ed a new and'useful Improvement" in Cleaning Tools amulettric' Fixturesfof which the following "is a.

Figure a cross section taken longitudinally through tlie clea iiiig' portion' of the meclianisnr and the Figures? to'9 show details ofthemechanism, shown in Figure ,6.

Referringno'w to Figures 1 to 9, the cleaning mechanism consistsof the brushes 5 of lambs wool or bristles on a leather or canvas stocking 6, mounted on springs or holders 7 and 7 2 mounted on the bracket 8 at point 9. The holders 7 are for the purpose of cleaning the shade 10 on the inside and the holders 7 are for the purpose of cleaning the shade 10 on the outside. These holders 7 and 7 2 are movable respectively outwardly and inwardly on their pivots at 9 by means of links 11 and 11 Holders 7 are provided with extensions 7 below the pivotal points 9 located in a substantially straight line with the holders. To the outer ends of these are attached the links 11, so that the extensions form levers by means of which the holders may be moved outwardly when the links are moved inwardly and downwardly. The holders 7 are similarly provided with extensions '2 below the pivotal points 9 located at right angles to the holders.

To." the] ,o tr: w s of t se; e ie' in attached he links-113, 6, that ah I th links are 'movedj i ithesa'me manner links 11f, the exte 1 1sio'ns 7 22 andfthtkfiholdersii may move inwardly. These'li iks 11, 1 1 are joined to a ring or' plate 12:, which in turii is movable downwardly against; the j spring 13 by nieaiisj of a string "of cord The cord, 14' fldjapl QVCl n this l eQbidllj by lever 15' fastened to the pole 16 by means of bracket 17.

No matter whether the brushes and associated parts are in line with pole 16 or at right angles there to, the cord 35 will, when lever 36 is operated, rotate in the same manner, due to the fact that the chain may be pulled parallel to the groove 31, even if the cord is pulled in the same direction or as is shown in Figure 1, at right angles thereto, as it would be if the part 22 and its associated parts are in straight line with the pole 16.'

hole 43 opens on the side of the pole 16 at 44 to permit the cord 14 to be manipulated from the outside by lever 15.

The operation of this mechanism is as follows:

When the shade 10 is located on the side of a wall as shown in Figure 5, the brushes are located as shown in Figure 1 and by pulling down the cord 14 by means of lever 15 the brushes are brought in close contact with the shade 10 and by closing and openin g the lever 36 the brushes are rotated forth and back over an angle of approximately 180; first by the lever 36 and then brought back in the original position by the spring 38. This action for cleaning the shade is the same when it is fastened in the ceiling or in an electric: fixture with the shade and lamp in a downward position and with the brushes and associated parts in line with the pole 16 as shown in dotted lines in Figure 3.

What we claim is:

1. In a cleaning tool for shades a combination of a plurality of brushes adapted to clean the outside of the shade and a plurality of brushes adapted to clean the inside of the shade, with means for operating said brushes in unison to close in on the shade and means for rotating the brushes around the shade.

2. In a cleaning tool for shades a plurality of brushes adapted to clean the shade on the inside and the outside simultaneously, means by which the pressure of said brushes against said shade during the cleaning operation may be regulated and means for rotating said brushes in unison around the shade.

3. In a cleaning tool for shades a plurality of brushes adapted to clean the shade on the inside and the outside simultaneously and means for rotating said brushes in unison around the shade, comprising a shaft attached to the brushes, a stationary support for said shaft, a spring surrounding said shaft, having one end fastened to the shaft and the opposite end to the support, a chain partly wrapped around said shaft for the rotation thereof against the tension of the spring.

4. In a cleaning tool for shades a plurality of hinged brushes adapted to clean the shade on the inside, a plurality of hinged brushes adapted to clean the shade on the outside, means for movingthe outside brushes inwardly and the inside brushes outwardly to close in on the shade comprising links fastened to the brushes at one end and with the opposite ends brought together at a common point, a holding ring for said links at the common point and a cord for operating said links, attached to said holding ring, to cause the brushes to move in unison to close in on the shade and means for rotating the ity of brushes adapted to clean the shade on the inside and the outside simultaneously,

means for rotating said brushes around the shade in unison and means for supporting said brushes in any position necessary for the convenient operation thereof, comprising a pole and a hinged portion on said pole.

6. In a cleaning tool for shades a plurality of hinged brushes adapted to clean the shade in the inside and the outside simultaneously, means by which the pressure of said brushes against such shade during the cleaning operation may be regulated, means for rotating said brushes around the shade and means for supporting said brushes in any position for the convenient operation thereof comprising a pole and a hinged portion on said pole to which the brushes are attached.
